im from Europe so I use Eurocodes (I believe ACI has similar control).
Lets say we have a column on a slab that is supported by walls (green lines in pictures).
Eurocodes give us 3 options for control perimeter (punching shear):
1. column is in the middle of a slab,
2. column is on / close to the edge of a slab,
3. column is at / close to corner of a slab.
Im asking what happens to a control perimeter when column is close to walls that supports a slab. Should I draw/use a control perimeter for punching shear as a combination of above options because its not 100% corner/edge column? Im talking about a bottom column in the last picture. The column is to close to the walls to use OPTION 1, but I think if I consider that control perimeter (punching shear of a slab) can appear right next to walls it is OK?
